Find a triplet that sum to a given value | C # program to find a triplet that sum to a given value ; returns true if there is triplet with sum equal to ' sum ' present in A [ ] . Also , prints the triplet ; Fix the first element as A [ i ] ; Fix the second element as A [ j ] ; Now look for the third number ; If we reach here , then no triplet was found ; Driver Code
